It annoys me greatly...

The X6 has the temp display, BTW. I'd like to replace mine.

In the manual on page 241 they provide instructions on bringing the engine to "operating temp"... "an uninterrupted drive of 6miles/10km"


In the E39M5, if the thermostat fails, the engine runs cool. No idiot lights, but the car is stuck in open loop mode due to the low temp, and will run very rich... emissions are up and power is down. The owner that notes his engine temp has been running cool can then think "say, maybe I need a new thermostat"... without temp gauges, you will not know. There are real and valid reasons for this information. Although I will admit not within the first 30 month lease BMW seems to be targeting as their prime demographic.
